Abstract: PURPOSE:To increase the life of a molten salt fuel cell by inhibiting the migration of the electrolyte from the surface of the gas-diffusing electrode to the cell jar wall and pipings by forming a boron nitride layer on the surface of the oxidizing or fuel electrode touching the electrolyte. CONSTITUTION:After a powdery mixture composed of 92pts. nickel carbonyl and 8pts. chromium powder s packed into a core material consisting of a nickel net, the thus formed body is sintered in a hydrogen stream at 950 deg.C to obtain a sintered body principally consisting of nickel. Next, a boron nitride powder is fixed by pressure to the surface touching the electrolyte of the sintered body used as the fuel electrode. On the other hand, after a mixture composed of 100pts. nickel carbonyl and 32pts. lithium carbonate is heated in air and then oxidized, the oxidized mixture is pulverized before the pulverized mixture is pressed and packed into a foamy nickel plate and then the thus formed body is sintered in air to make an oxidizing electrode. Next, a boron nitride powder is fixed by pressure to the surface of the oxidizing electrode touching the electrolyte to form a porous layer between the oxidizing electrode and the electrolyte.

Title: Measuring apparatus of amount of levitation of magnetic head
Inventor: YONEKAWA TAKAO
IPC: G01B7/14
Filed: 1988-09-28
Abstract: PURPOSE:To enable highly accurate measurement of an amount of levitation by a method wherein the projection of which height is variable is provided on a disk surface. CONSTITUTION:A disk 1 is rotated by a rotation driving unit 2 and a head 3 is levitated above the surface of the disk. Besides, a projection height control unit 4 impresses an impression voltage on a piezoelectric displacement element 7-2 through a brush 8 so as to control the height of a projection 7-1. Thereby the height (h) of the projection 7-1 is made variable from the surface of the disk in a range from 0mum to the height of suspension of the head. When the amount of suspension of the head 3 is measured, in this construction, the control unit 4 controls the impression voltage so that the projection 7-1 be raised at a speed of rising of the projection of about 0.01mum/sec until the projection 7-1 and the slider surface of the levitated head 3 come into contact with each other. When a head contact detector 5 begins to detect the contact of a head slider with the projection 7-1, the unit reads the impression voltage on the element 7-2 immediately and lowers the projection 7-1 below the disk surface. Based on this read impression voltage, the height (h) of the projection at that time is determined and the height of levitation of the head slider is determined.

Title: Pneumatic radial tire for heavy load
Inventor: IIDA HIROYUKI
IPC: B60C9/18
Filed: 1999-08-27
Abstract: PROBLEM TO BE SOLVED: To effectively restrain both cut separation and separation between plies. SOLUTION: A width Q of a residual belt ply 20d is made wider than a width R of an adjacent belt ply 20c. Since a widest belt ply 20b overlapped with a ply edge part J of the residual belt ply 20d is the same in a cord inclination direction as the residual belt ply 20d, and a rubber gage between the widest belt ply 20b and the residual belt ply 20d is thick, separation between the plies can be restrained. Since a cross angle of a cord inside the residual belt ply 20d is smaller than that inside the widest belt ply 20b and that inside the adjacent belt ply 20c, flexural rigidity in a peripheral direction is increased, and cut separation is restrained.
